empty score submissions

How do you deal with users who do not enter their name and click submit? It looks like they just have a blank area where there name should be. I don't remember having a problem with empty names while using mochiads.

Edit: Incase it makes a difference, the game (Fruit Slicer) is still pending activation approval on GamerSafe.

That is a nice game; and it is interesting to see that the Mochi leaderboards still work. I did not realize that the submit button was grayed out until the user typed in a name; probably because I instinctively entered a name when I saw the textbox.
